750 vs 850 vs 950 Holley

I suspect the blade angle was goofy on the 950. Maybe opening too far?
My 950 flows 1011cfm after adjusting blade opening...

What are the venturi and base plate bore diameters of your 950? Is it an HP Holley or different brand carb? Part #?

I understand. But you will find they flow better when the throttle blade is arked over the shaft about 7° or so. Depending upon the shaft width, of coarse.
Do the primaries and secondaries separately. vary throttle opening and watch the manometer.

I'll give that a try when I get the 1.45 main body carb on the bench.
